Many-Body Mobility Edge and Non-Hermitian Skin Effect in an Interacting Quasi-Periodic Spin Chain
Lavoisier Wah, Ayan Banerjee, Flore K. Kunst
Non-Hermitian many-body physics reveals a rich interplay between topology, localization, and boundary effects, yet their collective behavior in interacting disordered systems remai…
Spectral-topology-induced criticality in non-Hermitian fermionic metals
Ayan Banerjee, Julius T. Gohsrich, Flore K. Kunst
Quantum matter emerges from the interplay of fluctuations, topology, and entanglement, which - in equilibrium - governs quantized transport, universal criticality, and topological…
Multiple many-body localization transitions in a driven non-Hermitian quasiperiodic chain
Sanchayan Banerjee, Ayan Banerjee, Tapan Mishra +1
We investigate the fate of a many-body localized phase in a non-Hermitian quasiperiodic model of hardcore bosons subjected to periodic driving. While in general, the many-body loca…
The non-Hermitian skin effect: A perspective
Julius T. Gohsrich, Ayan Banerjee, Flore K. Kunst
The non-Hermitian (NH) skin effect is a truly NH feature, which manifests itself as an accumulation of states, known as skin states, on the boundaries of a system. In this perspect…
